To all whom it may concern;

Be it known that we, JULiUs' STUBTEVANT, a subject of the German Empire, and f JOSEPH T. \Vnmzmnn, a citizen of the i United States, both residents of New Ken-f sington, in the county of Westinoreland and State of Pennsylvania, have invented a new and Improved Tool, of which the following is a full, clear, and exact description.

Our invention is more particularly inten-fled for embodiment, in detachable hen: i dies for cooking utensils, but is capable of? embodiment in pliers and other gripping def vices.

The distinguishing features of our invention and the important structure of elements characterizing the illustrated examples will cific description hereinafter to be given.

Figure 1 is a longitudinal sectional ele-: vation of a detachable handle-for cooking utensils, illustrating the same in connection with a portion of a pan, the section being taken on the line 1-1 i-nFig. 2; Fig. 2 is a plan View of the handle; Fig. 3 is a longitudinal sectional view showing the invention a fragmentary plan View showing a portion of the lower handle.

In constructing a tool embodying our invention two handle members 10-11 are. formed, and suitable means provided for pivotally uniting said members. In the illustrated example the members are of channel form in cross section for the main part, the one member 11 being pierced as at 12*to provide an opening through which the companion member 10 passes, a rivet or pin 13 being provided to pivotthe members to gether. In the form shown in Figs. 1 and 2 the members are formed with jaws 1 l15 which are offset or disposed at an angle to the handle parts. The outer jaw 14;, which is formed on the under member 11, is substantially at a right angle to its handle. and is preferably curved transversely to approximately the curvature of cooking utensils of the most common size. As a tight fitof thejaw against the cooking utensil is not essential an approximate correspondence in the curvature between the jaw 14 and the pan 16 answers in practice. The inner jaw 15, which is formed on the member 10,- is formed to have a clearance atthecentral portion, as indicated at 17 the said jaw nww mye t n Patented res; 11,1213. Application' manages; 1912. {semi at; 705,364.

tacting with the pan 16 at the side edges of the aw'l5 only; To accommodate the head 18 with. which cooking utensils are usually provided. at the upper edge on the outside,

the jaws l415 are formed with depressionsv 19 andZO, respectively.

We provide novel means for locking t 'handlemmbers when the jaws are in the closed position gripping the pan or other article, said means comprising co-acting members carried respectively by the handle parts of the members, one of the co-acting locking elements being'movable, preferably by pivoting,-. so that it may, be moved into and out of engagement with its companion locking-element. Preferably the movable lockin' element consists of a ratchet bar, the body 20 of which is arranged lengthwise of which is zit-approximately right angles to the bod 20, said bar being pivoted at the angle thereof, as at 22, to the member 10. At the freeend of the body 20 an out wardly extending ofiset portion 23 extends through an opening 24: inthe member 10, the outer end of the offset 23 being provided with a finger piece 25 against which the thumb or finger of the user meg be pressed to rock the ratchet bar on itslpivot 22 for moving into and out of engagement the teeth 26 of the ratchet part 21 with the coacting locking element 27. The locking element 27 .is preferably formed integrally with the opposite handle member 11. The fixed locking element 27 is in the form of a stop or dog, which, in the examplelshown, is stamped from the material of the handle member 11 and extends inwardly toward the opposite handle member. The outer free end of the locking element 27 is bent desirably at an acute angle, and is forked to provide guide fingers 28 with an intervening slot 29, in which slot the ratchet part 21 of the movable locking element has guided movement. A spring is provided between the members 10 and 11, and we have so devised and arranged the spring that it serves the double function of normally tending to throw the movable locking element into engagement with its fixed locking element 27, and at the same time the spring-normally tends to separate the handle members 10 and 11 to open the jaws 14 and 15. The spring is shown as formed of wire, coiled between the ends. as at 30, from which coil extend the arms 31 o... The arm 31 is fixedly secured'to the member 11, preferably by stamping up a keeper 33 from the interior of the member 11, beneath which keeper the free end 34 of the arm 31 is clamped; the opposite arm 32 is bent laterally and passedthrough a hole, as at 35, in the body 20 of the ratchet bar to pivotally unite said spring arm with said ratchet bar. To limit the separating movement of the members -1l the free end of the offset ratchet part 21 of the movable locking element is formed with I oppositely bent lugs 36 which willbring up 'cally lock the jaws in the closed position.

In the form shown in Fig. 3 the jaws 1415 are given a form to constitute pliers.

the faces lat --15 being extended forwardly from the handle members 10 ll instead of being ofisct as in the first described construction. In all other respects the description given applies to the pliers shown in Fig. 3.

Having thus what we claim as new and desire to secure by Letters Patent is 1. A tool comprising handled-members formed with gripping jaws, means to pivot ally unite said jaws, coacting locking elements carried respectively by said members,

one of which locking members is movable into and out of engagement with the other, and a spring normally acting to engage the locking elements with each other and to open the handled-members.

2. A tool comprising handled-members formed with gripping jaws, means to pivotdescribed our invention,

ally unite said jaws, locking means consisting of co-acting elements carried respectively by said members, one of said locking elements being movable to engage the other,

and a spring tending normally to exert an i the ressure of the spring on one of the ban led-members being exerted on said member indirectly through the movable element of the locking means.

3. A tool comprising handled-members,

,opening pressure on said handled-members,

a ratchet bar pivoted to one member, a 00- v acting locking element carried by the other jaw and adapted to be engaged by the ratchet bar, anda sprmg having arms, one

of which is connected with the ratchet'bar and the other to the member-on which the co-acting locking element is carried.

4. A tool comprising handled-members,

-locking means :comgrising a ratchet bar pivoted to one han led-member, said bar having its ratchet member oflsetin the di--- rection of the other. handled-member, and the opposite free end of said bar extending laterally through the handled-member on which it is pivoted, and provided with a thumb piece, the free end of the offset ratchet member having oppositely projecting lugs, a co-acting locking element on the opposite handled-member, said co-acting element having an offset forked member in which the ratchet member of the pivoted locking element moves, and a spring having arms, one of which is secured" to the body of the ratchet bar adjacent-to the pivot and the other of Which-is secured to the opposite handled-member.

. In-testimony whereof we have signed our names to this specification in'the presence of two subscribing witnesses.
